Image analysis result of a case. a PD-L1 slide representing original image; b PD-L1 slide representing regional segmentation of the whole slide; c PD-L1 image representing regional segmentation result; d PD-L1 image representing cellular localization results. In regional segmentation, red and green areas represent TC (+) and TC (−) regions separately. In cellular localization, TC (+) (red), TC (−) (green), fibrocyte (yellow), lymphocyte (blue), and histocyte (pink) are shown separately. PD-L1 programmed death-ligand 1, TC tumor cells
